METAL RAILROAD-TIE.

Specification of Letters Patent.

Patented July 1, 1913.

Application filed October 30, 1912. Serial No. 728,652.

To all whom it may concern:

Be it known that I, JOHN MOODIE, citizen of the Dominion of Canada, residing at Vancouver, in the Province of British Columbia, Canada, have invented a new and useful Metal Itailroad-Tie, of which the following is a specification.

This invention relates to a metal railroad tie having provision for securing the rails thereto, and my improvements have been directed to a provision in the rail securing means for adjusting the rail laterally on the tie that the rails may be alined to those adjacent or the gage of the rails variedto the requirements of a curve. Further the rail securing means is removed from immediate proximity to the rail where the vibration is greatest and is such that a cushion of wood may be used 011 the rail seat, if desired. These several features of construction are fully described in the following specification, reference being made to the drawings by which it is accompanied, in which:

Figure 1 is a longitudinal elevation of the tie showing in section on the left the preferred type of rail holding means and on the right two variations of the same adapted to special requirements. Fig. 2 is a plan of the same. Fig. 3 is a cross section on A A in Fig. 1, and Figs. 4, 5 and 6 are detached perspective views to an enlarged scale of the several rail securing means.

The tie comprises a main or base portion 3 preferably of sheet metal and conforming in length and breadth approximately to Integral with orsecured to the base 3 on each side of the seat 6 of each rail 2 are grooved slideways l for the reception. of the rail holding means. The flanges of the rail 2 may either seat directly on the base 3 or on an interposed cushion 7 of wood, which may project beyond the width of and be recessed onto the base 3. The rail 2 is held down on its seat by flange holding members 9, which in their simplest form, as shown in Fig. 4, are plates adapted to fit the slideways 4L- and at one end 10 are reduced in width and tapered upward in thickness to fit the upper side of the rail flange.

Where a cushion 7 is interposed beneath the rail on its seat, as shown to the right in Fig. 1, the flange engaging portion 10 is projected upward above the plane of the groove, as in Fig. 5. For the outer rail of curves or elsewhere, when considered desirable, this flange engaging portion may be carried up to support the web of the rail, as shown in Fig. 6. These rail securing members '9 are forced tightly into engagement with the rail flange by tapered cotters 15 which are inserted throughcotter holes 16 cut in the plane of the groove 6 of the slideway, and after being driven tightly up, may be retained in place by a split pin inserted through one of a series of pin-holes provided in the cotter. An effective tie is thus provided which aflords facility for lateral adjustment of the rail thereon, as the cotter on one side of the rail may be slackened and the other tightened. This manner of adjustment enables the rails to be alined or the gage to be enlarged at a curve.

The rail holding members 9 are strongly supported in the grooves {L of the tie and are positive in their hold of the rail flange, and the securing cotters 15 not being in contact with, or in immediate proximity to, the rail are not subjected to intense vibration such as would slacken them.

I do not desire to be confined to the particular construction of the tie here set forth as the same may be modified to suit the requirements of manufacture. The ties may be stamped from sheet steel and folded to form the required rail seat and slideways, the arrangement of which forms an important feature of this invention, and the base member 2 may have its edges flanged to impart a certain measure of rigidity to it.

Having now particularly described my invention, I hereby declare that what I claim as new and desire to be protected in by Letters Patent, is:

In a metal rail tie, the combination with the thin flat metallic tie plate having upwardly' projecting integrally formed angled lugs arranged in pairs at each side of the rail space to form channel ways between the lugs of a pair, of rail base engaging members slidably mounted in the channel ways between said lugs, said lugs having cross apertures, and Wedges mounted in said name to this specification in the presence of iLDPGI't-IP'QS to force said rail engaging memtWo subscribing Witnesses.

ers home, and means for securin said Wedges from movement, all being arranged JOHN MOODIE' 5 substantially as shown and for the purposes \Vitnesses:

described. 7 ROWLAND BRITTAIN,

In testimony whereof I have signed my T MAY WHYTE.
